Like reference characters denote corresponding parts throughout the several views.

My calipers comprise the main arm l having the handle portion 2 and the biturcated end 3, the prongs 4l, 5 thereof being curved in opposite directions and being unequal in size, the prong being snialler than the prong el, each ot' said prongs having the usualY pointed terminations. To the prongs aforesaid the l( n arms (i, are secured by the set screws S, 9, said arms (5, 7 being bent or curved toward each other and their pointed extremities being adapted to coopcrate With each other.

lllhree separate and distinct measurements may be taken with the tool by applying the arms G, 7; the arm 14 and prong l; and the arm 12 and prong 5 to the Work. rlhe arms l2, 1lbeing movable longitudinally oit the arm l as ivell as adjustable pivotally permit a great variety of measurements to be taken by the tool and adapt it consequently to Work ot' various kinds.

lVhat is claimed is l. ln calipers, a main arm having one bifurcated end, the prongs thereof being oit unequal length and curved in opposite directions, said arms being formed with longitudinally extending slots, and means carried by said main arm for cooperation therewith, saidmeans including a pair o'l' indepemlently adjustable arms slidably secured in the slots of said main arm.

2. ln calipers, a main arm having one bilurcated end, the prongs thereof being of unequal length and curved in opposite directions, and a pair oi1 lesser arms adjustably secured to the prongs of said main arm, said lesser arms being curved toward each. other and being adapted to extend substantially beyond said main arm prongs in the plane oi the body portion ot the main arm.
